Solutions:

1. x + 1/x = 3(x – 1/x)

x^2 + 1 = 3x^2 – 3

2x^2 = 4

x = +/- √2

Option a.

2. The numbers vary from 9*2 till 9*33 and so, 32 cases. Option a.

3. nCx*x! = nPx. So, 56*x! = 336 or x = 3. So, nC3 = 56 or n = 8. Option c.

4. Side of the first triangle is 24, side of the second triangle is 12 and so on. So, 24/(1 – ½) = 48 cm will be the sum of the sides. So, sum of the perimeters will be 48*3 = 144 cm. Option a.

5. A leap year consists of 52 weeks and 2 days. If the year starts on a Sunday, it will have 53 Sundays and 53 Mondays. If it starts on a Monday, the year will have 53 Mondays. If it starts on Saturday, it will have 53 Sundays. So, 3/7 is the probability. Option c.

6. If x = 0, y = 3 and if y = 0, x = 4. So, option b.

7. Sum of the four prime numbers is 140. The only set that satisfies the given information is 29, 31, 37 and 43. So, the difference is 14. Option b.

8. Selling price is Rs. 15 per 1000 grams. To make 1000 grams of rasgulla, we need 375 grams sugar and 625 grams flour. Cost of 625 grams flour and 325 grams sugar is Rs. 9. If the cost of flour is 3x, the cost of sugar will be 7x per gram. So, 375*7x + 625*3x = 9

4500x = 9. So, x = 9/4500. Or, 7x*1000 = 14 Rs/kg. Option d.

9. Let the original price be x Rs/kg and the original amount bought be y kg. So, total amount spent is Rs. xy = 240. 0.8x * (y + 6) = 240

x = 10, y = 24. Option a.

10. 4/3*pi*r^3 = 1/3*pi*r^2*h

h = 4r. Option d.

11. Let the distance covered be 16x and the speed of scooter, car and train be x, 4x and 16x respectively. So, time taken to cover this distance will be in the ratio 16, 4 and 1 respectively. Time taken to velocity ratios will be 16/x:4/4x:1/16x and so, 256:16:1. Option a.

12. Let A do 1 unit per day. So, B does 2 units per day and total work is 15 units. A worked for 11 days and so, the remaining 4 units have been done by B. So, B has worked for 2 days. Option b.

13. A + B + C + D = 56 … (1)

B + C + D = 4.6A … (2)

A + C + D = 11B/3 … (3)

A + B + D = 2.5C … (4)

Using 1 and 2, we get A = 10, using 1 and 4, we get C = 16, using 1 and 3, we get B = 12. So, D = 18. Option d.

14. Let Saroj get Rs. 100. So, Raju gets Rs. 80 and Ram gets Rs. 70. So, Raju’s salary is greater than that of Ram by 1/7 or 14.28%. Option d.

15. pi*r^2^l = pi*r^2/9*l’. So, option d.
